Which one of the following statistics is calculated by finding the difference between the smallest and largest values in a set of data?

In statistics, we use measures of central tendency (mean, median, mode) to describe the 'typical' value in a dataset, and measures of dispersion (range, standard deviation) to describe how spread out the data is. The range is the simplest measure of dispersion. It is calculated as: Range = Highest Value - Lowest Value. It gives a quick, though sometimes rough, idea of the spread of the scores.
